The name of your company, a single phone number, and a short company description should be displayed on the front of the card. The author also recommends putting the website on the front (not the case in the example shown).
Don’t leave the back of the card blank; it’s a perfect place for a photo that shows off your work, as well as for additional contact information.
Add signs to the sides of your truck to turn it into a mobile billboard advertising your company. Make sure the phone number can be easily read from a distance.
